destination, < ea > . The ALC field of the access control register defines the number of
bits compared. If the upper bits of the source are numerically greater than (less
privileged than) the destination, they cause a memory management access level
exception. Otherwise, execution continues with the next instruction. If the MC field of
the access control register = 0, then this instruction always causes a paged memory
management unit access level exception.
